Know before you buy
This ratio indicates the percentage of nitrogen, phosphorus, and potassium. The higher nitrogen and potassium levels are specifically formulated to support lush foliage and strong root development in tropical plants and palms.
While it is optimized for tropical varieties, the balanced nutrient profile makes it safe for many other container plants. However, you should always check the specific nutrient requirements of your non-tropical species before consistent use.
Both methods are effective. Root feeding is best for general maintenance and long-term health, while foliar feeding allows for faster nutrient absorption if your plants show signs of deficiency.
The fertilizer is designed with high-quality, fully soluble ingredients that leave minimal residue. When used at the recommended dilution rates, it prevents the accumulation of excess salts in the soil that can otherwise damage delicate root systems.
Yes, this fertilizer is perfectly suited for continuous feed systems. Because it is highly water-soluble, it mixes easily into irrigation water for consistent, low-dose nutrient delivery.
